    摘要: The present discloses valve systems that include valve shift detection systems that can be employed to determine when a valve has shifted. In certain embodiments, the valve shift detection systems include a switch integrated into a valve block that may be closed upon shifting of the spool valve. In certain embodiments, the switch may include a component that completes a circuit upon contacting the valve. The valve shift detection systems also may include a controller designed to detect a voltage or current change produced by completing the circuit.

    摘要: An apparatus includes a downhole tool for conveyance in a wellbore extending into a subterranean formation. The downhole tool includes a modular cartridge assembly that includes a chassis assembly within a housing and that includes a flow line and an electrical pathway. The modular cartridge assembly includes a first connector at a first end and a second connector at a second end. The first connector and the second connector are in fluid communication with the flow line and are further in electrical communication with the electrical pathway.
